What is first communication satellite?
The first communication satellite was Echo NASA
What do you use to establish communication links in remote lacation?
To establish communication links in remote locations, one can use satellite communication systems, which provide reliable connectivity regardless of geographical barriers. Additionally, radio frequency (RF) communication, such as VHF or UHF radios, can be effective for short-range needs. Mobile cellular networks, if available, and portable Wi-Fi hotspots can also facilitate communication. Lastly, mesh networks can be deployed to extend connectivity among multiple users in an area.

What are the new trends in satellite communication?
Recent trends in satellite communication include the rise of mega-constellations, such as SpaceX's Starlink and OneWeb, which aim to provide global high-speed internet coverage. There's also a growing emphasis on small satellites and CubeSats, which are more cost-effective and versatile for various applications. Additionally, advancements in technologies like optical communication and artificial intelligence are enhancing data transmission rates and optimizing satellite operations. Finally, the integration of satellite communication with 5G networks is set to improve connectivity, especially in remote areas.
What are types of communication devices?
Communication devices include a variety of tools used to convey information, such as smartphones, tablets, and computers for digital communication. Traditional devices like landline telephones and radios also fall under this category. Additionally, specialized devices like walkie-talkies and satellite phones facilitate communication in specific contexts. Emerging technologies like smart speakers and wearable devices further expand the range of communication options available.
What is the down link frequency to earth?
The downlink frequency to Earth, in the context of communication satellites or spacecraft, refers to the frequency at which data is transmitted from the satellite to Earth. The specific frequency used can vary depending on the satellite system and the communication protocol being employed. Generally, downlink frequencies for satellite communication are in the microwave frequency range, typically between 1 to 50 GHz. The choice of downlink frequency is influenced by factors such as transmission range, atmospheric absorption, and regulatory requirements.
For satellite communication the frequency should be less than critical frequency?
For satllite communication the frequency should not be less than the critical frequency because in satellite communicaton high frequency is needed which is reflected by satellite but not by the ionosphere.
How satellite communication is different from communication relay?
For communication satellites the range is much higher than that of communication relay. Communication Satellite can cover up to several thousands of kilometers. For communication relay, the uplink and the downlink frequency is the same. But for communication satellites the uplink and the downlink frequencies are different in order to avoid interference.
What is the lower limit of frequency for satellite communication?
20 GHz
What is the telephone frequency range used for communication?
The telephone frequency range used for communication typically falls between 300 Hz to 3.4 kHz.
What is frequency of a satellite wave?
I never heard of a "satellite wave". If you mean the radio waves used by satellites for communication - well, like all radio waves used for such purposes, there is probably a large range of waves they can use.
Why is the up link frequency higher than the down link frequency in satellite communication?
The uplink frequency is higher than the downlink frequency in satellite communication because higher frequencies can carry more information and are less affected by interference and noise. This setup allows for efficient communication between ground stations and satellites, ensuring a reliable transmission of data.
What frequency range is from 3 GHz to 30 GHz?
The frequency range from 3 GHz to 30 GHz is classified as the Super High Frequency (SHF) band in the electromagnetic spectrum. This range is commonly used for various applications, including radar, satellite communications, and some wireless communication technologies. It is also part of the microwave range, which is crucial for both commercial and military telecommunications.
What are modulation techniques in satellite communication?
frequency modulation, preferably.
What is up converter in satellite communication?
Every information sent and received through satellite communication has to have an address to enable the communication process of signal delivery and reception. This naming of the signal is made in the form of a specific frequency. For example each TV channel operates on a unique frequency of it's own. When that frequency is called (tuned technically) out of a spectrum in that band, the chosen frequency gets selected. Since satellite transponders operate at very high frequency, modulation of the signal on to the carrier is difficult. Hence modulation is carried out at a much lower frequency. Such modulated signal is raised to the required frequency( name or address as stated above) that supports the satellite band and the transponder. The equipment used to elevate the frequency of the low frequency carrier (known as Intermediate Frequency) to the satellite transponder frequency is UP CONVERTER C.K.Vasudeva Bangalore
What is the correct terms when describing the frequency range of 3 kHz to 300 GHz?
Electromagnetic Frequency (EMF) & Radio Frequency (RF)
What is the radio frequency range of iridium satellite?
Iridium satellites operate in the L-band frequency range, specifically between 1616 MHz and 1626.5 MHz for their communication systems. This frequency range is used for both voice and data transmissions, enabling global coverage. The satellites utilize a unique polar orbit to provide connectivity across the entire Earth, including remote areas.
